COVERING FOR ROLLERS USED IN TEXTILE MACHINERY.

SPECIFICATION forming part of Letters Patent No. 433,493, dated August 5, 1890'. Application filed January 2, 1890. serial No. 335,670. (MocleL) To (0% whom, it may concern.-

Be it known that I, JAMES SHEPHERD, a subject of the Queen of Great Britain, residing at Davenport, England, have invented new and useful Improvements in Coverings for Rollers Used in Textile Machinery, of which the following is a specification.

My invention relates to coverings for roll ers used in connection with spinning, drawlng, roving, and other textile machinery, and has, mainly, for its object to provide a covering which is cheaper than the coverings of cloth and prepared calfskin now almost universally employed. v

The accompanying drawing illustrates, partly in section, a roll embodying my invention.

The roller is marked by reference-letters a and Z). aindicates the journals of an ordinary cast-iron double-boss roller, and Z) is a section through one of the bosses.

0 represents the finished outer surface of one boss, covered with paper, in accordance with my invention, being the part that must be varnished over to prevent the absorption of oil or grease.

cl (1 represent layers of thin dry paper wrapped tightly upon the roller oneover the other until the required diameter and necessary amount of cushion or elasticity is obtained. The last three or four layers or folds should be pasted or glued to each other, so as to obtain a strong outer working body or surface.

My improved covering possesses the necessary amount of elasticity and firmness to secure the production of good work, and can be run in a right or left hand direction without frayingor destroying the joint of the oovering, a fault common to all coverings made with short beveled joints.

To obtain a sufficiently firm and elastic covering for top rollers that are used in con nection with textile machinery and upon which so muolLdepends for the even quality and strength of the yarn, as well as the prevention of loss from Waste,I cover a metallic roller 01' a roller of any-other material, or rollers made up of a combination of materials,

over the parts intended to be covered with a thin tough paper in the form of ribbon or tape of the required Widths, and by suitable machinery or appliances I wind this paper ribbon or tape upon the roller, one fold close upon another, until a sufficient quantity has been wound on to give the necessary strength and elasticity of covering.

Layers of thin paper Wound close upon each other, though possessing considerable solidity, nevertheless retain a certain amount of elasticity, due to the number of fine interstices that remain between the unsecured folds of the paper, and it is this quality that renders paper covering for top rollers specially useful in connection with textile machinery.

In wrapping or winding the paper covering upon a roller the first layer must be secured to the rollerwith glue or other adhesive substance, and the last or finishing folds must be secured to each other in a similar manner, so as to give thickness, strength, and durability to the outer surface.

I wish distinctly to state that this invention is not for the purpose of making paper cylinders or tubes by wrapping paper one fold upon another to any required form or dimension, but for the specific purpose of forming elastic coverings for top rollers used in connectionwith textile machinery in the manner described.

\Vhen the covering of a roller is completed, I varnish over the outer surface and edges of the paper-folds with a quick-drying composition of shellac, dissolved in methylated spirit, or any suitable and quick-drying paper-varnish may be used. A good varnish will render the outer surface of the paper covering impervious to oil or grease, which covering is thus easily kept clean and very durable.

Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is- 1. A top roller for spinning and kindred machinery, covered directly by a continuously-Wound layer of thin tough paper, the same constituting an elastic covering, as set forth.

2. A roller for spinning and kindred machinery, covered With tough thin paper Wound coils being secured as set forth, and having [0 thereon layer upon layer, the first and last its outer surface varnished. layers being secured and the main body of intermediate layers being unattached but ly- JAMES SHEPHERD ing' closely together, all substantially as set Vitnesses:
